Posted 2021-05-12

      var xml =
        new XElement("Customer",
          new XElement("Name", "John Doe"),
          new XElement("Expiration", "2/1/2010"),
          new XElement("AmountDue", "$129.50"));
 
      var docxFile = @"..\..\doc.docx";
 
      using (var wpd = WordprocessingDocument.Open(docxFile, true))
      {
        var mainPart = wpd.MainDocumentPart;
        var xmlPart = mainPart.AddNewPart<CustomXmlPart>();
        using (Stream partStream = xmlPart.GetStream(FileMode.Create, FileAccess.Write))
        {
          using (StreamWriter outputStream = new StreamWriter(partStream))
          {
            outputStream.Write(xml);
          }
        }
